Stability Analysis and H∞ Output Tracking Control for Linear Systems with Time-Varying Delays

Abstract EN

The problem of stability analysis and H∞ output tracking control for linear systems with time-varying delays is studied.

First, by construction of a newly augmented Lyapunov-Krasovskii functional, a delay-dependent stability criterion for nominal systems with time-varying delays is established in terms of linear matrix inequalities (LMIs).

Second, based on the H∞ sense, the proposed method is extended to solve the problem of designing an H∞ output tracking controller to track the output of a given reference model.

Finally, three examples are included to show the validity and effectiveness of the presented delay-dependent stability and the H∞ output tracking controller design.
